Summary
Investing.com Canada published a Form 4 insider filing for Blackstone Multi-Strategy Hedge Fund L.P., reporting on a transaction by Gregory Adam Uffner, whose listed role is CLO (chief legal officer), with a transaction date of 22 September. The article is an automated filing notice carried by Investing.com and contains only the headline and standard Fusion Media disclaimers; it does not disclose the number of shares or units involved, the transaction price, or the resulting holding.

The same publication and related outlets carried additional Form 4 notices for the Blackstone fund. These list Riad M. Abrahams, identified as Director and CEO, with a filing dated 22 October; Philip Daniel Collins, Director, with a 22 September date; and William Simpson Gardiner, Chief Compliance Officer, also dated 22 September. Taken together, the notices indicate insider reporting activity across several senior officers and directors of the fund on or around the same dates, though the underlying transactions are not described in the available text.

Separately, Investing.com published Form 4 notices for Bluerock Private Real Estate Fund naming director Ramin Kamfar, with filings dated 21 September on Investing.com India and 22 October on Investing.com Canada. These relate to a different fund and are reported here only as related coverage from the same publisher.

Form 4 filings are required under U.S. securities law within two business days of an insider transaction, and they are typically used by investors to monitor insider buying and selling. Readers seeking the transaction type, quantity and價格 should consult the original SEC filing, as the coverage here does not provide those details.
